it's been a while....I have not posted anything on my blog in two years. It does not mean I stopped listening to music or building speakers and amplifiers. I was on sabbatical. Well, I used to work for small biotech company, which was acquired by large biotech company (swallowed, forcefully bought, insert your own...), and as it often happens, things change. Some people were let go, some were kept. I was offered to relocate into neighboring state, or take severance. I opted for severance. I got rid of most of my furniture, and gave away a lots of my audio stuff, kept just the best and moved my stuff into friends one-bedroom basement. Then I went on tour around the Australia and New Zealand. On the way back I stopped in Singapore and Dubai, and went for few month to good old Europe to visit relatives. Then I visited Banff in Canada. All together about nine months. Since then, I found another job in small biotech company and moved to 2 bedroom apartment in Germantown. I consolidated my two main systems into living room, so now I have two systems intertwined in one room. Here is how it looks.
System one...
